What 265/45R21 means
In the size 265/45R21, 265 is the section width in millimeters (10.43 in), 45 is the aspect ratio — the sidewall stands 45% as tall as the tire is wide, or 119.2 mm (4.69 in) — R denotes radial construction, and 21 is the wheel diameter in inches. That works out to an overall diameter of about 30.39 inches, turning roughly 664 revolutions per mile.
